Question

Express the exact value of csc 60 degrees, with a rational denominator.

Answer 1

Can someone plz help me with this

Answer 2

csc(60)=1/sin(60)

sin(60) has a well known value - do you know the value of sin(60)?

Answer 3

yes it is radical 3/2

Answer 4

yes, so we get:\[\csc(60)=\frac{2}{\sqrt{3}}\]

Answer 5

now just multiply the numerator and denominator by \(\sqrt{3}\)

Answer 6

that will get rid of the radical from the denominator

Answer 7

ok thank so much:), It makes perfect sense:)
